This site is no longer a small niche place, it gets a lot of traffic. The amount of illegal stuff you can't discuss on big forums is huge mainly because they can get shut down quite quickly if someone decides to take legal action.

Basically the site can be done for libel and so can you personally for the stuff you posted, the ISPs being required by law to submit your details to the authorities or something. But it's bad for the site to allow such speculation to go unchecked.
